WRENCH.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed August 30. 1907. Serial No. 390.822.

To all whom it may concern:

Be it known that I, WILLIAM C. SWEAT, a citizen of the United States of America, residing at Carlton, in the county of Okanogan and State of Washington, have invented new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to wrenches of the pivoted jaw type, .and one of the principal objects of the same is to provide improved means for adjusting the pivoted jaw of the wrench by means of a sliding wedge.

Another object is to provide a wrench of the character referred to in which the pivoted jaw is connected to the rigid jaw by a rule joint, and in which said pivoted member is j quickly adjusted by a sliding wedge and a These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation and partial section of a wrench made in accordance with my invention. Fig. 2 is an underside plan view of the same. Fig. 3 is a sectional view on the line 3-'3 of Fig. 1. Fig. 4 is a similar view on the line 4 4, .of Fig. 1.

Referring to the drawing for a more particular description of my invention, the numeral 1 designates the rigid jaw member of the wrench provided4 with an inclined inner face 2. Projecting from the jaw member 1 is a shank 3 provided with a recess 4, and at the bottom of said recess a series of ratchet teeth 5 are provided. The shank 3 is eX- tended, as at 6, and fitted into a handle 7. At one side of the extension 6 of the shank a recess 8 is provided. The pivoted jaw member 9 is provided with a roughened surface 10 and a projecting knuckle 11 which is seated in a recess 12 in the rigid member 1. The recess 12 is in the form of a partially circular groove which incloses the knuckle 11 and permits the pivoted jaw member 9 to be slid laterally out and into said recess. To hold the jaw 9 in pivotal connection with the rigid jaw 1, a housing 13 is secured by screws or rivets 14 to the rigid member 1. At one side of the pivotal connection of the jaw 9 an inclined wall 15 is provided.

Mounted to slide in the recess 8 in the ratchet and pawl.

shank portion 6 is anladjustableuwedgemcomprising a head 16 having an inclined wall 17 and a shank 1S provided with a recess 19 in which is pivoted a pawl 20 on the pivot pin 21, said pawl having a series of teeth 22 which engage the teeth 5 in the recess 4. A spring 23 is secured to the shank 1S by means of the screw 24, the end of said spring bearing upon the pawl 20 to hold the teeth 22 into engagement with the teeth 5. A projecting iinger piece 25 on the pawl eX- tends beyond the shank 18 in position to be readily operated by the Vingers of the user of the wrench. The portion 26 of the shank 18 of the sliding wedge is dovetailed, and iits the dovetailed recess 8 in the shank portion I 6, as shown more particularly in Fig. 4. A leaf spring 27 is screwed at one end to the upper wall of the housing 13 and has its free end disposed in engagement with the upper surface of the pivoted jaw member 9 at a point adjacent its rear end, said spring serving to normally retain the pivoted jaw member in opened position.

From the foregoing it will be obvious that a wrench made in accordance with my invention is of comparatively simplelconstruction, can be quickly operated to adjust the jaw 9 relatively to the jaw 1 by placing the thumb upon the projecting portion 25 of the pawl, and when released the spring 23 will move the pawl to engage the teeth 22 with the teeth 5.

My wrench is composed of few parts, is strong and durable, can be quickly adjusted and can be produced at slight cost.

Having thus described the invention, what I claim is:

1. A wrench comprising a rigid jaw having a transverse recess therein, a pivoted jaw means for holding said jaws in relative position, said pivoted jaw having an inclined face, a sliding wedge provided with a head to engage said face,- said sliding wedge carrying formed upon the shank of the rigid jaw for engagement by the teeth ofthe pawl.

2. In a wrench the'combination of a rigid jaw, a jaw pivoted thereto, said pivoted jaw having an inclined wall, asliding wedge having a head to engage said wall, a pawl pivoted to said sliding wedge, said pawl provided provided with a knuckle fitted in said recess, j

a spring pawl provided with teeth, and teeth 2 snow' with teeth, and a, projecting iinger portion, a, In testimony whereof I aiiiX my signature spring secured to the sliding Wedge and bearin presence of two Witnesses.

1n0 upon the pawi a series of teeth formed in T a iecess in the rigiil jaw member, and a dovem ILLIAM C SVEAT tailed shank on the sliding Wedge fitting a Witnesses:

dovetailed recess in the shank of the rigid DORA V. FEMLING,
